Coolant Inlet Pipe - 3.5L Ti-VCT: Removal

WARNING: Before beginning any service procedure in this service information, refer to SAFETY WARNINGS

NOTE: Use Motorcraft® Orange Antifreeze/Coolant. Do not mix coolant types. Mixing coolant types degrades the coolant corrosion protection and may damage the engine or cooling system.

NOTE: During normal vehicle operation, Motorcraft® Orange Antifreeze/Coolant may change color from orange to pink or light red. As long as the engine coolant is clear and uncontaminated, this color change does not indicate the engine coolant has degraded nor does it require the engine coolant to be drained, the system to be flushed, or the engine coolant to be replaced.
